IMPROVEMENT IN WATER-METERS.

had to the accompanying drawings, in which-. Figure 1 represents asideview of said watermeter. Fig. 2 represents a longitudinal centralsection through the same.

My invention relates to the combination of a spiral or grooved shaftwithin the waterpipe. with the working and indicating mechanism of awater-meter, by means ot'which.

t he water acts in a direct manner on the spiral or screw flanges ofsaid shaft, which latter perates the indicating mechanism, and whereby aperfect operation of the apparatus is ob tained by the use of a verysimple arrangement.

To enable others skilled in the art to make and use myinvention, I willproceed to describe its construction and operation.

A represents the pipe through which the water passes. In this pipe a Ishaft, B, is placed upon two screw center pivots, a, in such a mannerthat it can turn upon said pivots. The screw-pivots a pass through openboxes 1), within the pipe A, in which they can be adjusted with greataccuracy, and they are permanently secured in the desired position bymeans of the screw-nuts 0, while the openings :1 of said boxes admit ofa free passage of the water through the-pipe A. The shaft B is providedwith aspiral or screw flange,'(l, of the same diameter as the innerdiameter of the pipe A, against which the water, in passing through pipeA, acts andturns the shaft B on its axis. The shaft B is also providedwith an endless screw, E, which turns a wormwhcel, F, the latter beingsecured upon the shaft 9 within the chamber G. The chamber G is cast inone piece with the pipe A, but is so shaped that its connection withsaid pipe does not in any manner obstruct the free passage of the waterin a straight line through the pipe. The shaft 9 passes through astuffing-box in the side of the chamber G, and the gear-wheel II issecured to the outer end of the shaft. 9 and meshes with the gear-wheelI of the indicating mechanism, by means of which the quantity of waterin gallons or onbic'feet by units, tens, hundreds, &c., is indicated bymeans of the dials w my zon their respective dial-plates. Thiswater-meter presents great advantages by the simplicity of itsconstruction audits perfect operation. The meter is secured to thewater-pipes by means of the screws L M,and the water is not forcedaround any sharp angles or turns in the pipes, but passes in a straightcourse through them until it comes to act upon the spiral flanges O ofthe shaft P, whose movement is transferred in a direct manner to thegearing of the indicating apparatus. Another great advantage consists inthe facility with which-the bearings of the screw-pivots a can beadjusted so as to'cause the shaft B to turn f1 eely and to operate withprecision.

The apparatus is not liable to clog, as the passage of the water in astraight course through the pipe A will prevent any sediment fromlodging therein and will thus keep the pipe clear.

In transmitting motion of the shaft 13. to the wheel F, by means of theendless screw E, I change the fast motion of the shaft 13 to a slowmotion by one set of gears, which withordinary gear-wheels would requireseveral sets of wheels, and I thus materially simplify the apparatus.The water, in passing through the meter, enters the pipe A at t, andpassing through the pipe it turns the screw (J and shaft B and escapesat u, as indicated by the arrows.

my invention, what I claim herein as new, and desire to secure byLetters Patent, is-- 1. The shaft B, provided with the sczewflanges O,in combination with the 'endleis screw E, worm-wheel F, and indicating111(01- anism, substantially as and for the purposes described.

2. The arrangement of the shaft B with the pipe A, having its inlet andoutlet passages,

as set forth, in combination'with the chamber G of the main gear-wheelF, substantially in the manner and for the purposes described.
